These have been amazing for our dogs. Our 15 year old pittie/chow mix has dementia & gets freaked out when the sun goes down. It’s like she doesn’t know where she is & she can’t be still. When we started giving her these treats, she’d calm down within 20 or so minutes & she’d lay down on her bed & relax. They also help our nearly 9 year old pittie with her severe hip dysplasia.
